Halfdan Rydbeck
Profile
Expert in applied bioinformatics with 8+ years of experience in providing transparent and reproducible solutions for diverse areas of biological and medical research. I am innovative and have general drive to to find solution to technological problems. In my thesis project for MS in molecular biology I worked with cloning of a tumor supressor gene. I seek to understand the healthcare environment and external trends. I have emotional intelligence, strong communication skills and am a great teammate. I am dynamic and work very hard to achieve the intended result which has been decided from the start on time. I am not pretentious. I speak my mind and make it safe for others to do so. My collegues say about me that I am hardworking, joyful and problemsolving.
Objective
To use my scientific expertise to contribute to the efforts of the pharmaceutical industry towards the curation of disease. To take part in fulfilling the promises of genome editing.

Education
Halfdan did a “very good job as a senior engineer at NSC and is a responsible and pleasant person to work with” Professor Kjetil Sigurd Jakobssen, founder of Norwegin DNA Sequencing Center
PhD bioinformatics
Medical faculty, University of Oslo
Oslo, Norway
2012 - 2007
- PhD project with thesis title: Integrative epigenome analysis. Scripts developed in R and The Genomic Hyperbrowser was used to study the dependencies and select genes, based on genomic, epigenomic and transcriptomic alterations in samples from osteosarcoma and immune cells. The gene expression, promoter methylation and DNA copy number data were acquired by oligonucleotide microarray technology, and the histone modification data was acquired by technology based on chromatin immune precipitation and next generation sequencing, ChIP-seq.
- Developed and R package for clustering of genomic tracks.
